Rent & eviction protection

Is 3931-3933 24Th St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1900
2 or more units

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1900
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The 4-unit, 3-story multi-family residential building at 3931-3933 24th Street in Noe Valley, owned by the Mcfadden 1996 Trust-exempti, has experienced several significant maintenance and compliance issues in recent years. Most notably, during 2022, the property faced multiple active violations related to building maintenance, including problems with stairs, weatherproofing, and paint conditions, as well as concerns about smoke/carbon monoxide detector compliance. There were also serious plumbing issues documented through complaints about sewage leaks in April 2022, and problems with rear stairs requiring repairs valued at $8,000 were permitted in June 2022. The building's history includes an attempted major renovation in 2008 that was ultimately cancelled, which proposed adding one dwelling and two offices, along with extensive reconfiguration of existing units.

The building's commercial space has undergone changes over the years, including a controversial conversion from an ice cream shop to a bagel shop in 2010, which occurred without proper permits and generated complaints about noise and unpermitted equipment installation. More recently, from late 2023 through early 2024, there have been numerous reports of garbage, debris, and waste issues in the vicinity of the property, as documented in 311 calls to city services. While these external sanitation issues and sidewalk vendor complaints have been addressed by city services, they represent ongoing challenges in the building's immediate environment. The property has a long-standing history of maintenance and regulatory compliance challenges, with many violations and complaints remaining active as of the most recent records available.

Risk rating

How 3931-3933 24Th St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
3rdpercentile

Out of 1879 buildings in this neighborhood, 1823 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
